A new HRSEM approach to observe fine structures of novel nanostructured materials

A new approach for observing fine structures of novel thin, nanostructured materials called through the lens system (TTLS) is employed to observe interesting features on a variety of new, catalytically-important, hierarchically porous rattlespheres.
